Raised access floor

Abstract

In a preferred embodiment, there is a raised floor body having a plurality of parallel bottom arches, each arch defining a lower race thereunder, wherein the lower races are separated from one another by the arches. The raised floor body preferably includes at least one transverse top slot extending into the top surface of the body, thereby defining an upper race. The top slot may be disposed generally perpendicularly to the bottom arches. The body is further preferably provided with at least one vertical opening between the upper and lower races. A cover may be disposed over the top slot, and a liner may be disposed in the top slot. The body is preferably made at least partially from a cementitious material. The raised floor body may also include a mold for forming the cementitious material. The body may be cast in-situ or may pre-cast and installed as whole, by panels, or in individual modular blocks. The present invention also relates to a method for producing the raised floor.

What is claimed is: 
     
       1. A flooring system comprised of a plurality of cellular floor blocks having a top surface and a bottom surface each block comprising at least one arch defining a lower race in the bottom surface of each block, and at least one transverse top slot defining an upper race in the surface of each block, wherein said blocks are arranged in adjacent relationships selected from the group consisting of: a first arrangement wherein said lower races are disposed parallel to each other and said upper races are disposed linear to each other and perpendicular to said lower races; and   a second arrangement wherein said lower races are disposed linear to each other and said upper races are disposed parallel to each other and perpendicular to said lower races.   
     
     
       2. The flooring system according to claim 1 wherein said floor blocks are comprised of alpha hemihydrate. 
     
     
       3. The flooring system according to claim 1 further comprising anchoring means for maintaining said blocks stationary. 
     
     
       4. The flooring system according to claim 3 wherein each said block further comprises recessed outer vertical corners, wherein a plurality of contiguous recessed outer vertical corners of corresponding adjacent said blocks define a vertical cavity, and wherein said anchoring means is disposed in said vertical cavity.
